Kallion

Pain Points

01 Repeated and complex
preparatory setup

Repeated preparatory setup
caused by object change
and/or time lapse

  • 3D scanner
    connection
  • Preparatory
    setup
  • Start
    scanning
  • Camera calibration
  • Projector calibration
  • Manual adjustment of camera/projector

02 Limitations on the object
(size/color)

Limited object size
(200mm x 200mm)

Lens replacement for
object size change
Complex change procedure
and separate setup

Failed to scan
these parts
Scan result

03 Difficult usage requiring
experience and expertise

Solutions

01 Wide-range high-accuracy
calibration method

Korean Patent: 10-1813979

Actual optical
characteristics
of the lens

(Per-pixel ray
  calibration)

Focus length changes according
to pixel position

Competitor

Conventional method : Pinhole Camera Model

Kallion

Wide-range
calibration

Accurate
positions

New patented Per-Pixel Ray
Calibration technology

02 Precision scanning

Robust binary projection pattern for
high-accuracy 3D scanning

composite binary pattern
=binary Gray pattern + binary phase shift pattern

In-scan automatic accuracy
management

Iterative ray distance minimization:
Minimize RMS distance of intersecting rays while changing 5 variables
(3 rotations & 2 displacements)

03 Convenience

01. Instant Start

Do not require complex and time-consuming
calibration procedure. Factory calibrated and
accuracy is automatically managed.

After placing the object,
single click of the button
gives an all-automated
3D scanning experience.

02. Automatic background removal

03. Auto-Exposure / Automatic multiple exposure

Pixel Value = 255
(Saturation)

Saturation > Failure in Pattern Recognition

White pattern
projection

04. Direct 3D Printing

No mesh repair required. Automatic production of
2-manifold model guaranteed, which can be
directly fed into any 3D printers without any inconveniences.
